Summary

Photodynamic therapy (PDT) is suggested as an adjuvant treatment method to the surgery in peri-implantitis treatment. The primary goal of peri-implantitis therapy is the removal of the causative bacteria from the implant surface and surrounding tissues in order to improve the process of re-osseointegration and achieve long term implant stability. Accordingly, the aims of the study were to evaluate clinical, immunological and microbiological outcomes after surgical therapy of peri-implantitis following PDT.

Conditions

  • Peri-Implantitis

Interventions

PROCEDURE

Photodynamic (PDT) group

Mucoperiostal buccal and lingual incisions were made using a surgical blade under local anaesthesia. Full-thickness mucoperiosteal flaps were elevated buccally and lingually. In the photodynamic (PDT) group, after careful removal of granulation tissue and mechanical debridement of the implant surface, decontamination of implant surfaces and peri-implant tissues was performed using the photodynamic therapy, PDT (HELBO, Photodynamic Systems GmbH, Wels, Austria). The implant surface and the surrounding tissue were exposed to the laser light by means of fibres (HELBO ® TheraLite Laser HELBO ® 2D Spot Probe; bredent medical GmbH \& Co KG) for the 30s/spot, which operates on the wavelength of 660 nm and irradiance of 100 Mw. Bone augmentation and bio-resorbable membrane were applied in peri-implant defects using the bovine bone substitute and collagen membrane (Bio -Oss and Bio Guide, GeistlichPharma; Dembone). The mucoperiosteal flaps were repositioned and sutured.

PROCEDURE

Chlorhexidine (CHX) group

Mucoperiostal buccal and lingual incisions were made using a surgical blade under local anaesthesia. Full-thickness mucoperiosteal flaps were elevated buccally and lingually. In the chlorhexidine (CHX) group, after careful removal of granulation tissue and mechanical debridement of the implant surface 1% gel of chlorhexidine (Chlorhexamed® - Direkt) was applied on the implant surface for one minute and irrigated for 1 min by saline. Bone augmentation and bio-resorbable membrane were applied in peri-implant defects using the bovine bone substitute and collagen membrane (Bio -Oss and Bio Guide, GeistlichPharma; Dembone). The mucoperiosteal flaps were repositioned and sutured.
